5-6-2019 Firefox just sent out an update and now this extension works again. I was about to switch to chrome if this hadn't been fixed. I love this extension and it saves me a ton of money when shopping on Amazon. And The Camelizer developers quickly replied to my email when I said the extension had been disabled. Very happy with the fast response.

You don't realize how much you love something until it's gone! Sadly, they are temporarily off line due to equipment failure, but they are keeping users updated with every step of their way back to glory. This is a fabulous product, and they give it you for the low, low, cost of an email address. They've saved me hundreds in the 6 months I've used it.
